PPT-Photometric passbands Stars are (with some exceptions) well approximated by blackbodies.

overplotted Greg Bothun U Oregon UBVRI JHK filters UBVRI are within the visual part of the spectrum while J H and K are from the near IR Spectra of an A G and M type star are also shown. Types of exceptions. Checked exceptions:.  A checked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation.
